Yes, this exactly! Who among us has someone in our past that thought we were weird? Bill Gates was a nerd as a kid, so should someone have reported him? Unless this suspect has an official record of doing something bad, reports of him being “different” are just heresay. Heck, I am “different”.

“Remember, you are a unique individual, just like everyone else.”

Add chemistry to the “no interview” list.
